Abstract
Intercalates of calcium phenylphosphonate dihydrate with 1-alkylamines (C2–C10), 1-alkanols (C3–C10), 1,ω-amino alcohols (C2–C5), pyridine, morpholine, piperazine, aniline and 1-naphthylamine were prepared and characterized by powder X-ray diffraction and thermogravimetric analysis. The intercalates of alkanols and alkylamines are unstable at ambient conditions and the guest molecules are tilted to the host layers at an angle of 40°. The amino alcohol intercalates are stable and their basal spacings are very similar for all amino alcohols used and, in the case of ethanolamine and propanolamine, they contain co-intercalated water. Also arylamines and nitrogenous heterocycles form stable compounds. The general formula of these intercalates is CaC6H5PO3·xH2O·y(guest) and their basal spacings are from 15.39 to 15.78 A.
